So the Creator of "all this" flubbed. You've got more faith than me, my friend.
Perhaps He had a reason for doing what He did, and in this case we're just not savvy to what that reason is. Hopefully science will uncover a good explanation for the layout of the RLN. As for me, I'll trust that the Creator knew what He was doing. I have no reason to believe he made a mistake.
Fun thread, but not a productive use of my time.
It has. Evolution and recapitulation. Its layout in a fish or an (very young) embryonic person is fine. But the heart moves deeper into the chest, and the nerve has to follow the blood vessesls.
